Through thick and thin

I usually find it completely endearing that it is next to impossible to separate Franny and Cole.  We are finding, however, that this sometimes has it's drawbacks.  When Franny has a timeout on the stairs, Cole will always run and sit with her, and if he is restrained from going to her, he will scream and cry.   To prevent this, we tried to take Cole upstairs and lock the gate.  But, even this effort proved to be ineffective.  Cole figured out all too quickly that they can see each other in the mirror, through which they yell and laugh at each other.  Not much of timeout...
